Embodiment 1

[0038] A pressure-sensitive adhesive for label paper of high-performance self-adhesive film for refrigerator doors,

[0039] Prepared by reacting the components in the following amounts:

[0040] 80kg SIS, 50kg SBS, 45kg natural rubber, 15kg naphthenic oil, 15kg castor oil, 35kg aliphatic mineral oil, 42.5kg stearic acid, 42.5kg rosin glyceride, 12kg C5 petroleum resin, 45kg terpene resin, 2kg anti-aging agent.

[0041] Wherein, the terpene resin is a mixture of T-100 and T-120 terpene resin in a ratio of 1:1 by weight; the anti-aging agent is selected from any one of styrenated phenol, antioxidant 1010 or antioxidant 264. Yes, the antioxidant 1010 is selected in this embodiment.

[0042] Concrete preparation method comprises the following steps:

[0043] Step 1. Grind the rosin glyceride weighed according to the above ratio and add it to the stirring reactor, then add the same amount of stearic acid, heat up to 240°C, and keep the temperature for reaction for 4 hours;

[0050]

Embodiment 2-6

[0051] The concrete preparation method of embodiment 2-6 comprises the following steps:

[0052] Step 1. Grind the rosin glyceride weighed according to the ratio in Table 2 and add it to the stirring reactor, then add the same amount of stearic acid, heat up to 240°C, and keep the temperature for 4 hours;

[0053] Step 2. After cooling the reactor to 150°C, add naphthenic oil, castor oil, C5 petroleum resin, terpene resin, and pass N 2Protection, heat up to 200°C under stirring conditions, so that the added materials are in a molten state;

[0054] Step 3, continue to add SIS, SBS and natural rubber, stir for 2 hours, stop heating, and obtain a high-function self-adhesive pressure-sensitive adhesive for refrigerator doors.

Abstract

The invention discloses a pressure-sensitive adhesive for a high-function self-adhesive film of a refrigerator door. The pressure-sensitive adhesive is prepared by reaction of the following raw materials by weight: 80-120 parts of SIS, 50-80 parts of SBS, 40-60 parts of natural rubber, 15-30 parts of naphthenic oil, 10-30 parts of castor oil, 30-50 parts of aliphatic mineral oil, 40-50 parts of stearic acid, 40-50 parts of rosin glycerin ester, 10-20 parts of C5 petroleum resin, 40-60 parts of terpene resin and 1-5 parts of an anti-aging agent. According to the pressure-sensitive adhesive disclosed by the invention, stearic acid and rosin glycerin ester react to generate rosin glycerin stearate, which cooperate with other tackifier, castor oil for toughening modification and other components to prepare the pressure-sensitive adhesive. The pressure-sensitive adhesive has excellent water resistance, also has excellent persistent adhesivity when used at low temperature, and can meet various requirements for application to a refrigerator door. Meanwhile, the invention also correspondingly discloses a preparation method of the pressure-sensitive adhesive for the high-function self-adhesive film of the refrigerator door.

Description

technical field [0001] The invention relates to a glue, in particular to a pressure-sensitive adhesive used for a high-function self-adhesive film of a refrigerator door body and a preparation method thereof. Background technique [0002] Pressure Sensitive Adhesives (PSA) is a branch of the adhesive system, which is a viscoelastic body with both liquid viscous properties and solid elastic properties. Pressure-sensitive tape (PSAtape), also known as "adhesive tape", is a product that is pre-coated with a pressure-sensitive adhesive. It is characterized by uniform glue application and permanent stickiness, which can be bonded only by applying a certain pressure during use. According to the specific glue application form, pressure-sensitive adhesive products can be divided into single-sided tape and double-sided tape: double-sided tape mainly plays the role of connection; while single-sided tape is mainly used for packaging, bundling, fixing and surface protection.
